Historic Racing Groups

Competition cars covered by the Motorsport Australia 5th Category regulations are classified according to vehicle type, age and technological development into some 20 different groups to facilitate competition between similar vehicles. Some of these groups are further divided into sub-groups.

Sports and Racing Cars

Groups J, K, L, M, O, P, Q, R, F, V and F5000

This group is intended to depict early racing design and development to include the important field of significant excellence in design and workmanship defined as the “vintage period”. Vehicles eligible are racing and sports cars with a competition history established before 31st December 1930. One-off special type vehicles constructed at any time using major components manufactured prior to the end of 1930 are catered for in Group Jb.

This group is intended to cater for the pre and early post World War 2 period, including classically engineered factory constructed cars, local specials constructed on a one-off basis using production car components from the pre-war period, and some factory constructed cars which were modified during the group period, and fitted with engines from pre-war production cars. Vehicles eligible will be racing and sports cars with a competition history established between 1st January 1931 and 31st December 1949, using major components manufactured prior to 31st December 1940. One-off special type vehicles constructed at any time using major components manufactured prior to the end of 1940 are catered for in Group Kb

Lb – Racing Cars and Sports Cars This group caters basically for cars built for competition, either factory built or “one-off” specials. Lc – Square Riggers This group caters for “square rigger” sports cars (primarily MG TC) where it was common practice to remove the windscreen, mudguards and headlights and run as a racing car, at the whim of the owner.

Regularity Trials, Sprints and Hillclimbs

Regularity Trials

Regularity Trials is where the driver nominates a lap time and endeavours to maintain that time over a number of flying laps of a racing circuit. Each tenth of a second away from the nominated time scores penalty points. The driver with the least number of points wins, the driver with the most points and furthest from their nominated lap time comes last. The level of safety in Regularity Trials is good, as outright speed or lap time is not a consideration in scoring. A car passing you on the track is not perceived as beating you. This has the effect of competitors not trying to block or ‘dice’ with each other, as in racing or sprinting, and generally much safer competition results. In fact, blocking and dicing is not tolerated and will attract a penalty from the officials of the event. Competing vehicles can range from standard road cars to highly modified race cars, for safety participants are sent out onto the track with other compatible vehicles that lap at similar speeds.

Sprints

Sprints are mostly conducted at the recognised motor racing circuits around the country. Individual or small numbers of cars are released at regular intervals onto the track and generally complete several laps at a time racing against the clock, and not the other drivers out there at the time. Whilst sprints are not actually races, they give participants a great feel for what it is like to drive at high speed competitively around a race track and provide a fabulous test for car and driver alike. Competing vehicles can range from standard road cars to highly modified race cars, for safety participants are sent out onto the track with other compatible vehicles that lap at similar speeds.

Hillclimbs​

Hillclimbs are one of the oldest forms of competitive motor sport and enjoy a strong following throughout Australia. The essence of hill climbing is that it is a single car on the track at a time running against the clock. The tracks used are sometimes dedicated hill climb venues, or often short sections of closed public roads that have been upgraded for the purpose. Hill climbs cater for nearly every category of Motorsport Australia recognised vehicle and vary from standard road cars through to dedicated and specialist hill climb cars exhibiting the pinnacle of motor sport technology from around the world. Part of the skill involved in hill climbing is learning to drive the car quickly without the opportunity to warm tyres and brakes. It therefore proves to be an invaluable training ground for drivers in all aspects of car control. Competing vehicles can range from standard road cars to highly modified race cars.
